Ok so the title of this post is mildly misleading because the GMAT is big, but hundreds of thousands of people have survived and overcome this giant so it is not insurmountable.
As a college senior, I somehow managed taking the GRE, the grad school application process, 2 theses and a host of other fun and academic related things so I know that it's definitely possible for me to still have fun, get my work done and do well on the GMAT. Nonetheless, balance in life is hard when you try to do everything.
Looking around at the world more since college, I've seen lots of really successful who don't work at maximum capacity and tons of sort of successful people who put in little to no effort at all. This has allowed me to start to relax my idea of what hard work really is or how time consuming it has to be. Also, for the last 5 months, I've been only working a 40 hour week which was something really unusual to me. I really didn't have the option of working more if I wanted to mostly because there was no more work to do and if there was work, it was boring so I didn't want to do it. This left lots of free time for fun so the balance in life has swung towards "life" instead of work.
Now, I'm back in a job where I could work 24/7 if I wanted to. At the moment, I'm still enjoying my "life" so don't want to work too much. But now GMAT and grad school applications need to make their way into that life. I know that I will have to make sacrifices and not be able to do everything to buckle down and study for the GMAT. I know I can do it, but I've always hated missing out on fun things.
The GMAT isn't insurmountable, but it definitely means that key sacrifices will need to be made. I just have to keep looking at the end goal of 2 great years in grad school, but first I have to tackle the GMAT Giant.
It's all about finding that balance between things that need/have to be done and the things that I want to do. But, that's life and we all keep learning.
